Method for Managing Fuel and Lubricant Performance Requirements

A cost-effective method of managing requirements for the performance properties of fuels and lubricants (FLs) is presented. Performance requirements are detailed in the form of conceptual and empirical models, along with their quantitative expression through highly informative indicators showing the propensity of FLs for various transformations, practical evaluation, specification, implementation, effectiveness evaluation, and modification. The proposed method ensures improved equipment life cycle efficiency based on the use of FLs. Examples are given to illustrate some provisions of the new method as applied to the properties of motor fuels and hydraulic fluids.
